中国2009年胃癌发病与死亡分析

An Analysis of Incidence and Mortality of Stomach Cancer in China,2009

[目的]评估中国肿瘤登记地区2009年胃癌的发病与死亡情况。[方法]按中国肿瘤登记中心制定的审核方法和评价标准对全国104个肿瘤登记处上报的2009年肿瘤登记数据进行评估,共72个登记处的数据入选,计算胃癌的发病率、死亡率、顺位、构成、累积率;根据全国1982年人口普查的人口结构和Segi’s世界人口结构的标准计算人口标准化率。[结果]2009年胃癌新发病例30949例,死亡病例22120例。病理学诊断比例为76.14%,只有死亡医学证明书比例为2.95%,死亡/发病比为0.71。全部地区胃癌发病率为36.21/10万(男性49.61/10万,女性22.50/10万),中标率为17.85/10万,世标率为23.93/10万,累积率(0～74岁)为2.94%。城市地区发病率为30.20/10万,中标率为14.15/10万;农村地区发病率为48.57/10万,中标率为26.31/10万。全部地区胃癌死亡率为25.88/10万(男性34.64/10万,女性16.91/10万),中标率为11.86/10万,世标率为16.38/10万,累积率(0～74岁)为1.89%。城市地区死亡率为21.15/10万,中标率为9.07/10万。农村地区死亡率为35.60/10万,中标率为18.25/10万。[结论]胃癌是威胁我国居民健康的主要癌症之一,其在男性、女性和城乡地区之间存在明显差异,应根据实际情况有重点地开展防治工作。

[Purpose] To evaluate stomach cancer incidence and mortality in China in 2009. [Methods] On basis of the criteria of data quality from NCCR, data submitted from 104 registries were checked and evaluated. There were 72 registries’ data qualified and accepted for cancer registry annual report in 2009. Descriptive analysis included incidence and mortality stratified by area （urban/rural）, gender, age group and cancer site. Chinese population census in 1982 and Segi’s population were used for age-standardized incidence/mortality rates. [Results] The total new stomach cancer incident cases and cancer deaths were 30 949 and 22 120 respectively in 2009. The morphology verified cases accounted for 76.14%. About 2.95% of incident cases only had information from death certifications and mortality/incidence ratio was 0.71. The crude incidence rate of stomach cancer in registration areas was 36.21/105 （49.61/105 for male,22.50/105 for female）, age-standardized incidence rates by Chinese standard population （ASR China） and by world standard population （ASR World） were 17.85/105 and 23.93/105 with the cumulative incidence rate （0～74 years old） of 2.94%. The stomach cancer incidence and ASR China were 30.20/105 and 14.15/105 in urban area while in rural area they were 48.57/105 and 26.31/105 respectively. The stomach cancer mortality in Chinese cancer registration areas was 25.88/105 （34.64/105 for male and 16.91/105 for female）, ASR China and ASR World were 11.86/105 and 16.38/105 , and the cumulative mortality rate （0～74 years old） was 1.89%. The stomach cancer mortality and ASR China were 21.15/105 and 9.07/105 in urban area, while in rural area they were 35.60/105 and 18.25/105 respectively. [Conclusion] Stomach cancer is one of the major threats to the health of our residents, which is different between urban and rural areas in China. Prevention and treatment should be carried out according to the practical situation.
